Its about my wife. A couple months ago she had an injury after getting a microdermabrasion treatment on her chin. The injury became infected and she was prescribed antibiotics. This seemed to be clearing things up. But over the last week or so it seems to have come back. This time its not only on her chin but on her forehead, back, chest arms, legs. There are a bunch of sores which first appear like pimples but then turn into open sores with puss that bleed. What could this be? She will see her doctor Monday but we were just dismissed outright at a dermatologists office and the diagnosis - picking and scratching. The dermatologist however, did not know about the original injury and infection from med equipment because he would not let my wife explain. Was he correct?
